GATE-HINGE.

SPECIFICATION forming part of Letters Patent No. 227,838, dated May 18,1880.

` Application nienMmh 22,1880. (No model.)

To all whom it may concern.-

Be it known that I, WILLIAM W. ROBIN SON, of Ripon, county of Fond du Lac, State of Wisconsin, have invented a new and useful Improvement in Gate-Hinges; and I here by declare the following to be a clear, full, and exact description, reference Abeing had to the accompanying drawings, making a part of this specication, and in which- Figure lisa perspective view. Figs. 2 and 3 are plan views of the hinge in two positions.

' My invention relates to hinges which allow Vthe gate to be opened in both directions; and the invention consists in certain details of construction, as hereinafter more fully described and claimed.

In order that those skilled in the art may make and use my invention, I will proceed to describe the eXact manner in which I have carried it out. A i

In the said drawings, A is a gate, and B the gate-post from which it is hung. The upper hinge orrthe gate is located about in a central vertical line, and is a simple pintle-hinge.

The lower hinge is constructed as follows:

` 1t is attached to the post by means of a plate,

, greater-length than the other.

a, at the end of which -is pivoted, as seen at b, a plate, c, bent so that in a cross-sectional line it is three sides of a parallelogram. To the end of this plate c, at d, is pivoted a plate, e, of a construction somewhat similar to plate c, one of the short sides, e', being of unequal- The long side of plate c is bolted to the gate, as shown, and

r 3 5 when the gate is closed the end of side e of plate e lies against plate c' and braces the gate. The end of plate a has a stop, p, on its end, against which the stop p on the end of plate a abuts when theI gate is opened in the direction shown in Fig. 3, thus, by an end-thrust, preventing any cross strain on the plates. i

It will be observed that in the `construction of this hinge, when the gate is opened in either direction, the central vertical line of the gate is so thrown at the base from a central position that the gate will automatically close by its own weight.

From the construction described it will be seen that this hinge can be made very cheaply, as it is made of plates ot" thin rolled or other iron and does not require any particular torgings or castings, which are required in other hinges of this class. 1
